凯歌牌3瓦高传真晶体管扩音机是上海无线电四厂1964年新产品之一.本机与凯歌牌4B4型晶体管汽车收音机配套使用,所以使用电源设计为14伏直流,在汽车、拖拉机上运用时电源可由车上的蓄电池和发电机供给,其电压变化范围从10.5～14.8伏时能正常使用,因此本机无论在车辆上,户外运用时都很方便。对农村、滚塌、林区、山区及凡是有蓄电池等直流电源、汽本一、拖拉机所到之处都能运用。本机的电性能在负荷4欧时,额定
Kay card 3-watt high-fidelity transistor amplifier is one of the new products of Shanghai Radio IV Factory 1964. This machine is used with Kay song 4B4 transistor car radio, so the power supply is designed to be 14VDC, when used in automobile and tractor It can be supplied by batteries and generators in the car. The voltage can be normally used in the range of 10.5 ~ 14.8V. Therefore, this machine is very convenient for outdoor use in vehicles. On the countryside, rolling down, forests, mountains and where there are batteries and other DC power supply, a steam tractor everywhere you can use. The machine’s electrical performance at 4 ohm load, rated
